A representative for Arizona State University said school officials have suspended Tau Kappa Epsilon's chapter operations while they investigate an unregistered Greek event that has many on campus offended.

Pictures from the event, coined "MLK Black Party" by the group, show members and guests dressed in basketball jerseys, flashing gang signs and even drinking from watermelon cups.

"This isn't appropriate at all and you really have no business dressing like this on a day that's sort of revered for African-Americans," said ASU senior Frank Hogan after seeing some of the pictures.

"I think this represents the ignorance that still exists today. This is just one example of the kind of things that occur here," stated Kaajal Koranteng, also a senior.

A spokesman from the local chapter, who would only identify himself as Cole, would not comment on the party or investigation. Rather, he told CBS 5 News to contact the national organization for TKE.

"We are aware of the situation. We have been contacted and we have been in contact with the local chapter and the university," explained Patrick Gleason, the director of Compliance and Housing for the national organization, based out of Indianapolis.
